If there are individuals or large groups who are forced to live around each other and if either party or both parties hate each other due to conflicts or past injustices commited by either or both of due to repulsion to each other (I.e various tribes or individuals find other tribe's or individual's practices abhorrent). Then is there a way to peacefully dissolve the situation and work towards peacebuilding ?
Since there is a likelihood the hating parties or aggrieved parties would definately not be open to changing their views or would have a strong sense of righteousness , would such conflicts not be solvable by normal means ?
Are there any mainstream academic psychology , sociology or social science informed theories or practices that could help
